Description
Najdluzszy czas trwania patentu do 18 czerwca 1940.W wypadku, opisanym pod A w paten¬ cie Nr 2273, dotyczacym izolowania sulfo¬ kwasów naftowych z kwasu odpadkowego, odpadki kwasowe zobojetnia sie weglanem wapniowym lub wapnem gaszonem w odpo- wiedniem stezeniu.Przy tej reakcji czesci asfaltowe, beda¬ ce pierwotnie w roztworze koloidalnym kwasnym, zostaja wytracone w postaci mie¬ szaniny siarczanu wapniowego i asfaltu.Mieszanina ta tworzy gesta mase pla¬ styczna w wyzszej temperaturze (ponad 50° C), a twardai krucha w zwyklej tempe¬ raturze i przedstawia, jako taka, znakomity materjal, zastepujacy naturalny asfalt.Zawarty w tej mieszaninie bitumen moze byc przez wyciaganie odpowiedniemi roz¬ puszczalnikami, jak benzyna, benzolem, chloroformem, dwusiarczkiem wegla i t. d. wydzielony w stanie czystym ii uzyty do fa¬ brykacji laków, masy izolacyjnej i t. p. ma- terjalów. PLThe longest duration of the patent is June 18, 1940. In the case described under A in Patent No. 2273, relating to the isolation of petroleum sulfa acids from spent acid, the acid waste is neutralized with calcium carbonate or slaked lime at the appropriate concentration. the asphalt parts, originally in an acidic colloidal solution, are precipitated as a mixture of calcium sulphate and asphalt. This mixture forms a dense plastic mass at higher temperatures (over 50 ° C) and a hard and brittle mass at ordinary temperatures. and presents, as such, an excellent material to replace natural asphalt. The bitumen contained in this mixture can be extracted with suitable solvents, such as gasoline, benzene, chloroform, carbon disulphide, and so isolated pure and used for the production of lacquers, insulating mass and other materials.
